Patent number: 10752225Abstract: A computer that includes a processor and memory that stores instructions executable by the processor. The instructions may include generating, at a host vehicle, a roadway friction map by: detecting a velocity change of a target vehicle; calculating friction data based on the velocity change; and storing the friction data.Type: GrantFiled: February 8, 2017Date of Patent: August 25, 2020Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventor: Scott Varnhagen

Patent number: 10703359Abstract: A computer is programmed to predict, based at least in part on a stored road topology for a predetermined vehicle route, a vehicle body orientation based on lateral, longitudinal, and vertical accelerations predicted for the route. The computer is programmed to, based on the predicted vehicle body orientation, adjust at least one of an orientation of the vehicle body and an orientation of an object in the vehicle as the vehicle traverses the route.Type: GrantFiled: January 27, 2017Date of Patent: July 7, 2020Assignee: Ford Global Technologies, LLCInventors: Scott Varnhagen, Schuyler Cohen, Johannes Strom, Ghassan Atmeh, Alice Kassar

Patent number: 10077054Abstract: The present invention extends to methods, systems, and computer program products for tracking objects within a dynamic environment for improved localization. Sensing devices are utilized to gather data about a vehicle's environment. In cases where the sensor data has become degraded, such as data indicating that lane lines have become degraded, obscured, or nonexistent, the vehicle computer system uses previously detected sensor data to estimate the speed and direction of travel of moving objects. The computer system then estimates the location of the moving objects after a specified period of time based on the estimated speed and direction of the moving object. The computer system utilizes this information to localize the vehicle within the dynamic environment and to control the configuration of the vehicle.Type: GrantFiled: April 13, 2017Date of Patent: September 18, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Bibhrajit Halder, Scott Varnhagen

Patent number: 10065636Abstract: A vehicle and associated method for calculating tire saturation is provided. The method may include the stability control computer calculating slip ratio and longitudinal force for the tire, calculating tire longitudinal stiffness by dividing longitudinal force by slip ratio, calculating tire saturation from tire longitudinal stiffness, and the stability control computer altering dynamic control of the vehicle based on calculated tire saturation. The stability control computer may calculate tire saturation from a tire saturation membership function which includes a first tire longitudinal stiffness value representing an unsaturated tire, a second tire longitudinal stiffness value representing a saturated tire, and a function line connecting the first tire longitudinal stiffness value to the second tire longitudinal stiffness value.Type: GrantFiled: June 23, 2016Date of Patent: September 4, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Scott Varnhagen, Ming Lang Kuang
